Gunnar Hillert upgraded the coherence-community/coherence-spring repository to modernize its technology stack and improve security, stability, and release management. He migrated the project to Spring Framework 6.1.15, Spring Boot 3.4.0, and Spring Cloud 2024.0.0, ensuring compatibility with the latest Java ecosystem and reducing vulnerability exposure. Gunnar enhanced the platform’s documentation by adding a comprehensive Auto-Configuration chapter, clarifying configuration and exclusion processes for users. He also prepared the codebase for the Coherence Spring 4.3.0 release, updating dependencies, release notes, and build configurations. His work demonstrated depth in Java, Maven, dependency management, and technical documentation.

December 2024: Delivered a major platform upgrade for coherence-spring, modernizing the stack with Spring Boot 3.4.0 and Spring Cloud 2024.0.0, plus targeted release readiness for Coherence Spring 4.3.0. This included a minor test adjustment to use java.util.Base64, a new Auto-Configuration documentation chapter to guide configuration and exclusions, and comprehensive release preparations with version bumps and build/release config updates. Business value includes improved ecosystem compatibility, security and performance readiness, clearer configuration guidance for users, and a faster, more predictable release cadence.
